|Title:||Genotype by Temperature Grouping Interaction for Farrowing Rate at First Insemination||Contributor(s):||Bunz, A M G (author); Bunter, K L (author) ; Morrison, R (author); Luxford, R G (author); Hermesch, Susanne (author)||Publication Date:||2019||Open Access:||Yes||Handle Link:||https://hdl.handle.net/1959.11/28651||Open Access Link:||http://www.aaabg.org/aaabghome/fullproc23.php||Abstract:||This study examined the effect of temperature grouping (T-group) on genetic parameters for farrowing rate from first insemination (FR). Further, this study investigated if genotype by T-group interaction for FR exists. The lowest FR was observed in T-group 1 and 3, which were both characterised by high mean maximum temperature (>29⁰C) prior to mating. The heritability of FR across all T-groups differed only marginally from each other and were low (0.03, 0.00, 0.03, 0.02, and 0.03 for T-group 1, 2, 3, 4 and 5, respectively). Genetic correlations between FR recorded in different T-groups were generally positive and high (>0.70), with the exception of the genetic correlation for FR between T-group 1 and 5 which was lowly negative and close to zero (-0.10±0.27). This is an indication that FR in T-group 1 and T-group 5 were two genetically different traits and should be treated as separate traits in pig breeding programs.||Publication Type:||Conference Publication||Conference Details:||AAABG 2019: 23rd Conference of the Association for the Advancement of Animal Breeding and Genetics, Armidale, Australia, 27 October-1 November||Source of Publication:||Proceedings of the Association for the Advancement of Animal Breeding and Genetics, v.23, p. 155-158||Publisher:||Association for the Advancement of Animal Breeding and Genetics (AAABG)||Place of Publication:||Armidale, Australia||ISSN:||1328-3227||Fields of Research (FoR) 2008:||070201 Animal Breeding||Fields of Research (FoR) 2020:||300305 Animal reproduction and breeding||Socio-Economic Objective (SEO) 2008:||830308 Pigs||Socio-Economic Objective (SEO) 2020:||100410 Pigs||Peer Reviewed:||Yes||HERDC Category Description:||E1 Refereed Scholarly Conference Publication||Publisher/associated links:||http://www.aaabg.org/aaabghome/|
